- The accuracy of predictive equations for calculating resting energy expenditure (REE) in elderly people has been questioned. Aging is associated with progressive declines in REE, which partly is explained by loss of fat free mass (FFM). Against this background we aimed to identify the most accurate predictive equation for REE in octogenarian men, taking body composition into account and using indirect calorimetry as reference value. REE was measured in 22 men (mean age 82.6 +/- 0.3 years) and compared with six predictive equations: two based on FFM and four based on body weight, height and/or age. FFM was derived from Dual-energy X-ray absorptiometry analyses. Spearman's rank correlations showed a moderate to high positive monotonic correlation (r = 0.62 to 0.79) between measured and calculated REE (all p < 0.005).The mean calculated REE was significantly different from measured REE for all equations except Mifflin-St Jeor. A calculated REE within 10% of measured REE was considered acceptable and the equations of Mifflin-St Jeor, WHO and Harris-Benedict captured 64%, 50% and 45% of the participant, respectively. The Mifflin-St Jeor equation had the lowest root mean square error (138 kcal), followed by the equation by Harris-Benedict (189 kcal) and WHO (220 kcal). The equations from Luhrmann, Henry and Cunningham predicted REE rather poorly in our study subjects, with e.g. <40% of the individuals within 10% of measured REE. Our results indicate that the Mifflin-St Jeor equation (using FFM) is the most accurate equation estimating REE in these octogenarian men. Harris-Benedict or WHO equations are potential alternatives if information on FFM is unavailable, although their accuracy on an individual level is limited.

Tidskriftsartikel (refereegranskat)abstract
- Background:Adherence to dietary patterns has been associated with cognitive decline and dementia, but studies are inconsistent.Objective:Dietary patterns, i.e., WHO recommendations (Healthy Diet Indicator), a Mediterranean-like diet (modified Mediterranean Diet Score, mMDS), and a low carbohydrate high protein diet (LCHP), were related to incident cognitive dysfunction, as indicated by Alzheimer's disease (AD), all-type dementia, and all-type cognitive impairment, in a cohort of 1,138 elderly Swedish men.Methods:Dietary patterns were derived from 7-day records. Risk relations were calculated by Cox and logistic regression analyses, adjusted for potential confounders. Sensitivity analysis was performed in a subpopulation (n = 564) with energy intake according to the Goldberg cut-off. Results:During a mean follow-up of 12 years, 84, 143, and 198 men developed AD, all-type dementia, and all-type cognitive impairment, respectively. There was no association between Healthy Diet Indicator and any of the outcomes. Hazard ratios associated with 1 standard deviation (SD) increment in the LCHP score were 1.16 (95% confidence interval [CI]: 0.95, 1.43) for AD and 1.16 (95% CI: 0.99, 1.37) for all-type dementia. mMDS was not associated with dementia diagnosis. Odds ratio (OR)/1 SD increase for mMDS and all-type cognitive impairment was 0.82 (95% CI: 0.65, 1.05). In the subpopulation OR for mMDS and all-type cognitive impairment was 0.32 (95% CI: 0.11, 0.89).Conclusion:We found no strong associations with development of cognitive dysfunction for any of the dietary patterns investigated. However, there was a potentially beneficial association for a Mediterranean-like diet on the development of cognitive dysfunction in the subpopulation.

- Samband mellan kost och demenssjukdom är inte tydligt fastställda. Studiens syfte var att prospektivt undersöka hur tre olika kostmönster relaterar till utvecklingen av demenssjukdom, inkl. Alzheimers sjukdom (AD), eller alla typer av kognitiv störning hos äldre friska män.

Vitamin D is not associated with incident dementia or cognitive impairment : an 18-y follow-up study in community-living old men

- Background: Vitamin D has been implicated as being important for maintaining cognitive function in old age. Results from longitudinal studies examining the association of vitamin D with incident dementia and cognitive impairment have been inconsistent. Objective: We investigated the relation between vitamin D, assessed in 3 different ways, and the risk of dementia. Design: We measured plasma 25-hydroxyvitamin D [25(OH) D] with the use of high-performance liquid chromatography-mass spectrometry, assessed dietary vitamin D intake with the use of 7-d dietary records, and created a vitamin D-synthesis genetic risk score (GRS) at baseline (1991-1995) in a cohort of 1182 Swedish men (mean age: 71 y). In a maximum of 18 y (median: 12 y) of follow-up, 116 men developed Alzheimer disease, 64 men developed vascular dementia, and 250 men developed all-cause dementia. An additional 80 men declined in cognitive function as assessed with the use of the Mini-Mental State Examination. Adjusted HRs and ORs were calculated with the use of Cox and logistic regressions. Results: The mean +/- SD plasma 25(OH) D concentration was 68.7 +/- 19.1 nmol/L. Plasma 25(OH) D, dietary vitamin D intake, and vitamin D-synthesis GRS were not associated with any cognitive outcomes (crude and adjusted HRs and ORs were similar to 1.0 for all continuous exposures). The adjusted HR for all-cause dementia was 0.88 (95% CI: 0.59, 1.31) in men with plasma 25(OH) D concentrations <= 50 compared with >75 nmol/L. The adjusted HR for all-cause dementia was 0.92 (95% CI: 0.63, 1.32) for the lowest compared with highest tertiles of vitamin D intake. The adjusted HR for the continuous GRS for all-cause dementia was 1.04 (95% CI: 0.91, 1.19). Conclusion: In this cohort study, we show that there is no association between baseline vitamin D status and long-term risk of dementia or cognitive impairment over an 18-y period of time.

Tidskriftsartikel (refereegranskat)abstract
- Background: Comparative studies on dietary patterns and long-term mortality are sparse.Objective: The objective was to examine the relations between 10-y mortality and adherence to the World Health Organization dietary guidelines [Healthy Diet Indicator (HDI)], a Mediterranean-like diet, and a carbohydrate-restricted (CR) diet in elderly Swedish men.Design: Dietary habits were determined by 7-d dietary records in a population-based longitudinal study of 924 Swedish men (age: 71 ± 1 y). The HDI score (–1 to 8 points), the Mediterranean Diet Score (MDS; 0–8 points), and the CR score (2–20 points) were calculated for each participant. Nonadequate reporters of energy intake were identified (n = 413). Mortality was registered during a median follow-up of 10.2 y. Cox proportional hazards regression, with multivariable adjustments, was used to determine the effects of adherence to each dietary pattern.Results: Two hundred fifteen and 88 subjects died of all-cause and cardiovascular disease, respectively. In all individuals, risk relations to mortality for each SD increment in the scores were observed for only MDS, with an adjusted hazard ratio (HR) of 0.83 (95% CI: 0.70, 0.99). Among adequate dietary reporters (n = 511), adjusted HRs for each SD increment in scores were enhanced for MDS (ie, 0.71; 95% CI: 0.55, 0.92) for all-cause mortality and 0.63 (95% CI: 0.42, 0.96) for cardiovascular mortality. Corresponding HRs for CR diet score were 1.19 (95% CI: 0.97, 1.45) for all-cause mortality and 1.44 (95% CI: 1.03, 2.02) for cardiovascular mortality.Conclusion: Adherence to a Mediterranean-like dietary pattern reduced mortality, whereas adherence to a CR dietary pattern appeared to increase mortality in elderly Swedish men, especially when only adequate dietary reporters were considered.
